Grant Peterson's touch isn't magic, they were produced by the thousands in an Asian factory.

Still, modification seems a little drastic. Even if you get the mounts rebrazed, you need a repaint afterwards. Depending on the hand behind the torch, I can't imagine it would cost you less than $150. For that you get a lingering sense of guilt for modding a frame, a fancy new color, steering geometry optimized for a very different wheelsize and a price tag that's a third of the way to a new 650b bike.
